Inhalation: Move person to fresh air, seek medical attention if discomfort persists or symptoms worsen
Skin Contact: Wash with plenty of water and mild soap for several minutes, remove contaminated clothing, seek medical advice if irritation develops
Eye Contact: Rinse cautiously with water for at least 15 minutes, lift eyelids to ensure thorough rinsing, get medical attention quickly as irritation can persist
Ingestion: Rinse mouth, do not induce vomiting, drink water if conscious, seek immediate medical attention
Suitable Extinguishing Media: Foam, dry chemical powder, CO2, do not use water stream on burning liquid
Special Hazards: Can give off carbon oxides and other toxic fumes during combustion
Protective Equipment: Firefighters need self-contained breathing apparatus and protective clothing
Additional Advice: Move containers away from fire area if safe, keep cooling water on adjacent containers, avoid inhaling fumes
Personal Precautions: Wear protective gloves, goggles, lab coat, respirator if necessary, stay upwind of spill
Environmental Precautions: Prevent from entering drains, soil, or water sources, notify local authorities if large releases occur
Spill Cleanup: Absorb with inert material such as sand or earth, shovel into suitable containers, ventilate area after cleanup, wash spill site thoroughly using soap and water
Handling: Work in well-ventilated area, avoid dust formation, avoid personal contact with skin, eyes, or clothing, do not ingest or inhale, use appropriate safety equipment
Storage: Store in tightly closed container in cool, dry, well-ventilated place away from incompatible substances such as strong oxidizing agents, acids, or bases, keep away from direct sunlight or heat sources, clearly label containers, limit access to trained personnel
Engineering Controls: Use fume hood or local exhaust, maintain adequate general ventilation, use spill trays and eye wash stations
Respiratory Protection: Use approved respirator if exposure levels exceed workplace standards or if adequate ventilation is not possible, particularly during large scale or open handling
Skin Protection: Wear protective gloves made of nitrile, neoprene, or similar material, wear appropriate lab coat or apron
Eye/Face Protection: Chemical safety goggles or full face shield
Hygiene Measures: Wash thoroughly with water and soap after handling, keep food and drink away from work area, remove contaminated clothing and equipment before leaving the area
Appearance: White to off-white crystalline powder or solid
Odor: Mild sweet or aromatic odor
pH: Not applicable (solid)
Melting Point: Around 74-76 °C
Boiling Point: Decomposes before boiling at atmospheric pressure, may boil above 310°C under special conditions
Solubility: Slightly soluble in water, easily soluble in most organic solvents such as ethanol, ether, acetone
Density: 1.17 g/cm³
Vapor Pressure: Low at room temperature
Flash Point: Estimated above 170°C
Partition Coefficient: log Kow around 1.3
Chemical Stability: Stable under recommended storage and normal temperatures
Reactivity: Inert toward most materials within normal operating conditions, strong oxidizers may cause violent reaction
Hazardous Decomposition: Forms toxic carbon monoxide, carbon dioxide, and potential organic vapors upon strong heating or burning
Conditions to Avoid: Excess heat, open flame, direct sunlight, sources of ignition, contact with incompatible chemicals
Incompatible Materials: Strong oxidizing agents, acids, bases, halogens
Acute Toxicity: Oral LD50 in experimental animals above 1000 mg/kg; expected to have low acute oral toxicity in humans
Chronic Effects: No data on repeated exposure in humans, limited animal studies show minimal long-term effects at low doses
Skin Sensitization: May cause mild skin irritation on prolonged or repeated contact
Eye Effects: Causes redness, irritation, possible watering and stinging
Inhalation: Dusts or fumes can irritate nose and throat, high levels may cause coughing or discomfort
Carcinogenicity: No evidence to classify as carcinogenic based on known studies
Mutagenicity: No mutagenic effect found in standard laboratory tests
Other Data: Individuals with allergies or asthma may be more sensitive to chemical effects
Ecotoxicity: Not acutely toxic to aquatic organisms at levels expected from normal industrial use, care should be taken to limit large releases
Persistence and Degradability: Expected to be biodegradable, breaks down in soil and water through microbial action over days to weeks
Bioaccumulation: Low potential based on molecular structure and log Kow
Mobility in Soil: Moderate mobility, can leach in high concentrations but quickly adsorbs to soil organic matter
Other Adverse Effects: Prevent spills and minimize environmental contamination to protect water and soil quality
Waste Treatment: Collect and send to chemical disposal facility or high temperature incinerator approved for hazardous waste
Container Disposal: Rinse containers, puncture or crush before disposal, comply with local environmental regulations
Precautions: Do not dump into sewers, natural bodies of water, or open environment
Special Advice: Consult with certified chemical waste disposal contractors for specific procedures and legal requirements
UN Number: Not classified as hazardous for transport by most regulatory bodies
Transport Hazard Class: Not restricted; treat as chemical cargo
Proper Shipping Name: 2-Phenyl-1,3-Propanediol or Hydratropic Alcohol
